Abstract
Over 90% of the United States land area is termed as rural. Additional traffic fatality rates in rural areas are approximately 2.5 times higher than in urban areas Despite the enormous land area clear and safety risk, many rural roadway authorities lack sophisticated resources for crash mitigation. The spatial dispersion of crashes in rural areas makes it difficult to reliably identify high-risk locations. GIS-HSR tools. an ESRI geoprocessing script. was developed using modern statistical and analytical techniques, including sliding window analysis and Empirical Bayesian (EB) statistics. It is designed to leverage the current computer and spatial processing techniques while limiting necessary user interaction. The tool makes use of existing geometric traffic and law enforcement crash response data reporting normally available to the roadway authority allowing for low cost implementation by practicing professionals. GIS-HSR tools is an efficient solution to several rural safety prioritization challenges. This tool implements both modeling and crash count-based screening methods, offering flexible and accurate prioritization options for safety engineers.
